Millimetre-scale magnetocardiography of living rats with thoracotomy

Causes of heart failure can be investigated by tracing imperfections in electrical current propagation on the millimetre scale; however, the spatial resolution of current magnetocardiograph methods are limited to the centimetre-scale. Here, the authors report a millimetre-scale nitrogen vacancy-base...

Sammanfattning:Causes of heart failure can be investigated by tracing imperfections in electrical current propagation on the millimetre scale; however, the spatial resolution of current magnetocardiograph methods are limited to the centimetre-scale. Here, the authors report a millimetre-scale nitrogen vacancy-based quantum sensing to measure the magnetic field generated by the heart of a living rat, from which the cardiac electrical currents can be extrapolated.
